Qantas Airlines is considering to sell half-stakes of its poorest performing freight enterprises to Australia post.

Both of the airlines' freight businesses - Star Track Express and Australian Air Express - did not live up to their high-growth promises. The global economic crisis contributed to the slow demand and weak performance of these two freight services.

A few analysts from Macquarie Equities said the freight operating performances within Quantas, with a total of $288 million, may result in a sale to Australia Post.

Two months ago, Qantas disclosed during a briefing that a takeover management with government-owned Australia Post is pending for review.

However, Qantas said yesterday that despite a continuance with the "partnership review", the airlines remained focus on the two businesses.

The analysts predict that Australia Post may be the key buyer after the newly installed chief Ahmed Fahour declared its prospects to enter into a parcel and express delivery industry in Australia.

''Should Qantas wish to exit these investments, Australia Post would be the natural buyer,'' the analysts said.

The analysts suspected that Qantas concentrates more on Qantas' flying and cargo businesses, and that a proposed joint venture of its freight services with Australia Post may be scrutinized.

Analysts further suggests that Qantas should sell its business directly to Australian Post rather than a joint venture to reduce operating costs.

Meanwhile, a spokesperson of the Australia Post said it holds regular talks with Qantas regarding the two businesses, with the condition of Qantas "continuing in their current form."

Star Track Express endured a 29 per cent downturn in net profit to $18.6 million on the last financial year while Australian Air Express did not even reach its target net last year. Both companies attributed their net loss on weak freight volumes.
